Tektronix 491 band C (solid state version) varactor diodes

Miguel Work


I´m searching for a replacement diode for a TEKTRONIX 491. Is marked as MA45601. I have replaced with a BB405, and PLL now works well, but If is possible I would like to put original ones or equivalent, ceramic body Ghz band diodes, in the MACOM catalog I don’t see it.
Any know where to find them?

I have already built a prototype that uses an I-Phone to take pictures. I have not done enough with this to answer most of these questions. The I-Phone does a presentable job. It can be done with some additional work.
